I like the Entertainment Book but can't justify its price tag. For free, though, I can definitely use it enough to justify that purchase! Right now most of the Entertainment Books are going for $15 shipped. Through Cashbaq, you get a $5 bonus for signing up PLUS a $10 rebate for buying the Entertainment Book...so it is basically FREE! I won't get the check until March, but the money is already sitting in my account. And I will use Cashbaq instead of Ebates in the future if I can get a higher percentage back.
Here's my referral link if you want to give it a try, but you certainly don't need to use that to sign up.
